What is Geologic Time ?

The Geological Time Scale (GTS) is a system of chronological measurement that relates stratigraphy to time. Geologic Time is the 4.6 billion year history of Earth. Geologists have created a time scale to organize Earth’s history into eons, eras, periods, and epochs. The geologic time scale began to take shape in the 1700s.
